    摘要： Alarm and warning systems and methods for detecting the approach of objects to a prohibited area and eliciting a warning or an alarm when such objects are detected. The bird radar systems and methods are for use at airports or wind parks to provide a warning or an alarm when birds are approaching. The detection system includes one or more processors configured to detect and track a bird and to generate an alarm or alert when a tracked bird enters an alarm zone inside a radar coverage range, wherein the one or more processors are configured to dynamically arrange the alarm zone within the radar coverage range using real time information.

    摘要： A Frequency Modulated Continuous Wave, FMCW, radar system is provided. The radar system comprises one or more antennas configured to transmit and receive FMCW radar wave signals for scanning for objects within a full circular detection coverage range, and processing circuitry configured to provide scan data based on transmitted and received FMCW radar signals and azimuth position of the antenna(s). In a first aspect, the processing circuitry is configured to generate first type radar plots, where each first type radar plot holds range, radial velocity and return energy data for one or more detected objects, and configured to generate second type radar plots, where each second type radar holds azimuth, range and return energy data for one or more detected objects. In the first aspect, the processing circuitry is also configured to generate full data type radar plots by combining first and second type radar plots having corresponding range data, whereby each full data type radar plot holds azimuth, range, radial velocity and return energy data for one or more detected objects. In a second aspect, the processing circuitry is configured to generate full data type radar plots based on obtained scan data, and the processing circuitry is further configured to select irregular type radar plots from full data type radar plots, where the irregular type radar plots have velocity data representing positive and negative radial velocities within an observed radial velocity range. The processing circuitry may also be configured to generate object tracks or unmanned aerial vehicle, UAV, tracks, where each object/UAV track is based on at least two irregular type radar plots. In a third aspect, then for the plots of a generated object/UAV track, the processing circuitry is configured to determine an outer energy sum of return energies for range cells representing positive and negative radial velocity signals within a first and a second outer radial velocity range, and to determine a center energy sum of return energies for range cells representing radial velocity signals within a center range of the observed radial velocity range, and/or a total energy sum of return energies of range cells representing all observed radial velocity signals. In a fourth aspect, there is provided an unmanned aerial vehicle, UAV, system, which UAV system comprises a control station for controlling a first co-operating unmanned aerial vehicle, UAV, and a radar system configured to scan for objects within a detection coverage range and to provide scan data indicative of objects detected within the coverage range. The first UAV may be provided with a transponder holding identification information, ID, and the first UAV and the control station may be configured for exchanging transponder data.

    摘要： A method and system for real-time and automated detection and classification of aerial objects, such as e.g. UAVs, on a radar plot level from digital radar images, wherein the digital radar images are created from radar return signals obtained by a conventional radar such as e.g. a continuous wave radar (e.g. FMCW radar), a phased-array radar, or a pulse radar, as opposed to using specialized micro-Doppler radars for classifying UAVs based on the Doppler effect created by the rotors or propellers of the UAVs. Further, the method and system allow for tracking the UAVs based on the digital radar images.

    摘要： An avian detection system for determining risks of collision between a collision object and bird objects includes avian radar system(s) providing a first type of information data relating to objects detected, and a transponder receiver receiving transponder data transmitted or broadcasted by transponders provided at the collision objects. Processors are configured to receive first type of information data corresponding to the detected objects and provide radar plots. The processors are further configured to receive the transponder data and provide transponder plots, to create and store a number of object tracks based on the provided radar plots and transponder plots, with each track holding object data corresponding to or determined from data of matching plots, and to determine one or more risks of collision or collision risk levels for the collision object based on object data of a plurality of the obtained object tracks.
